Aim and feature of courseAim and feature of course

Electricity, something difficult to see with the human eye, will be visualized and explained with a combination of computer graphics, narration, and images.
There are lecture questions at the end of each section for this course. By working through the questions, you can see how much you have come to understand about the basics of electricity.
Even with know prior knowledge of electricty, learn about three-phase AC and basic concepts.
The focus will be on practical applications instead of difficult formulas, so that those who wish to learn the basics of Electricity will be able to do so more easily.
